To all whom it may concern:

Be it known that I, FRANK A. RoB Nson, a citizen of the United States,resid ng in Brooklyn borough, city and State of New York, have inventedcertain new and useful Improvements in Type-Writing Machines, of whichthe following is a specification. t

This invention relates to typewrlting'machines provided with. means toenable a number of work-pieces towbe quickly arranged on the platen,particularly where the workpieces are of difi'erent widths and arrangedwith their leading edges at different positions of advancement, as iscommon, for in making entries on statements, bills, or the like,arranged on the platen together with a loose-leaf ledger sheet, or

' other record sheet. I

' any one of a series space distance inxadvance of the preceding sheetplaced on'the' ma This invention is an improvement on the inventiondisclosed in the co-pending application, Serial No. 89,303. Saidapplication shows a paper chute or guide at the introductory side of theplaten, on which the work-pieces may be placed, and advanced bring theirleadin ing board exten front face of the platen.

The present invention provides improved means to assist in quickly andaccurately adjusting lating board and then holding them againstaccidental displacement. For this purpose there is provided asheet-ho1ding and gaging dev ce' or prise a graduated seriesOfsheet-holding bosses orstuds arranged in a row at the collating board,and adapted to enter correspondmgly positioned openings provided in themargins of the work-sheets. Said bosses .may be arranged atline-spaceintervals, so

that a work-sheetmay beheld thereb at of positions, each a ine- Thus aposition.

and gaging the sheets on thGCOlr devices, each of which maycom the same.

of bosses, the bar being mounted on the face of the collating board andadjustable thereon toward and from the printing line, whereby saiddevice maybe adjusted to a, ruled sheet or printed form, so thatthehorizontal rulings or positions forprinting lines on the sheet willregister with the printing line of .the machine.

adjusted thereon and held by a row or rows of; saidstuds enteringcorresponding openings in the margin or'rnargins of the sheets. Thesheet may beheld in position by onehand of the operator, while with. the

other hand the overlying sheet, which may beof less width, is adjustedover the first sheet. A plurality of *thewgaging bosses hold. theoverlying sheet square. with the platen and in register; with thefirstshcet, thus overcoming the usu'aldifliculty of alining theoverlying sheet and-holding it from shifting until the sheets areclamped to the platen.

Other features and advantages will. hereinafter appear.

In the accompanying drawings I Figural-is a front perspective, v1ew,fshowing a paper carriage of an Underwood typewriting machine, withthe-present invention applied thereto.. a Fig.2 is-a part sectionalendelevation of Fig. is a front, elevation show-ing; the method ofadjusting the work on the machine. Fig. 4 is a sectional end.elevation,=showing the work-in adjusted position. i b Fig. 5 is afragmentary view. of gage ar. The roller-platen l0, has-its: axle 11journaledin a platen. frame 12,, said frame mounted for case-shiftingmovement-on the carriage frame '13; "The platen mayybe ro tated by handwheels 14 on the platen-axle, or by means of the usual line-spacingmechanism, comprising a. line-space ratchet wheel 15' fixed to the"platen axleaand driven step the platen to print on the work-sheets.Feed rolls 19 bear against the platen and-cooperate therewith to advancethe worksheets when the platen is rotated. The feed rolls may be thrownoff the platen by. means of a key 20 connected through a link 21 to arock arm 22 on a rock shaft 23. The latter is provided with flats 24,which when the key 20 is depressed, operate levers compris ing arms 27and 25. The arms 25 carry a shaft 26, on which the feed rolls aremounted. When the shaft 23 is rocked, the arms 27 are movedrearwardly bythe flats 24,.to

move the feed rolls ofi the platen.

The means for positioning the worksheets on the platen will now bedescribed. Such means comprises a paper chute or guide 30 at theintroductory side of the platen. Said chute has at its lower end anexte'nsibrrBl curved around the platen, and spaced therefrom to providea passage-way for the work-sheets, so that when a sheet is placed on thechute it may be pushed for- .ward and guided around the lower surface ofthe platen, and upwardly astthe printin line, to bring its leading e dgeon a sheetco lating table 32. The chute 30 is provided with end flanges33 for gagin the lateral edges of the work-pieces, t e' collating board32 also being provided with sheet-.

gaging end flanges 34, which'are preferably in alinementwith the gages33. The chute 30 may be supported by a bar 35, extending between theplaten frame ends and forming part of the. platen frame; The chute maybe further, supported by a tie rod 36 of the platen frame, which rodextends through openings in the flanges 33.

The sheet-collating board or table 32 may be supported by brackets 37mounted on the rod 36, to which brackets is secured a bar 38 extendinglengthwise of the platenandconnected by screws 39 to the collatingboard. The bar 38 may be slotted to receive the screws 39, permittingthe board to be adjusted. toward or from the platen. The collating boardis formed with sheet-supporting surfaces 40 at its-ends, which surfacesare offset or raised with respect to the central orbody portion 41 ofthe board. The surfaces 40 are also extended upwardly a substantialdistance beyond the central portion of the board, to provide ample suport for the work,- and to facilitate the ad ustment of the work on saidboard. The construction thus far described may be substantially likethat disclosed in the co-pending application 89,303, above referred to.

The means for gaging the work-sheets and holding them inadjustedposition comprises gaging bars 42, mounted on the sur- 43 to enter aseries of circular openings formed in the margin of the work-sheet. Theroundedshape of the bosses facilitates the quick adjustment of thesheets thereon, and also permits the sheets to be readil disengaged,thatis, the bosses are self-freeing from the sheets.- The rows of bossesare parallel with the ages 34, and may be equally spaced, pre erably atline-space intervals determined by the spacing of the teeth of theline-space ratchet wheel. There is thus provided a graduated series ofsheetgaging and holding bosses by which a worksheet may be gaged andheld by a number of'said bosses, with its leading edge at any one of. anumber of difierent positions of advancement beyond the printing line,and while the sheet is retained by the feeding rolls 19; the sheet beingthen released from said bosses while it is still retained by the feedrolls. As the sheet, in each adjusted osition, is held by. a number ofbosses, it is thereby squared tothe printing line on the platen. Eachposition of adjustment isalso an exact line-space distance in advance ofthe preceding position, which arrangement is of particular value insecuring uniform spacing of the typewritten lines on asheet which isplaced. on the machine a ,n-umber of times, each at a differentlinespace position. Each gage bar 42 is adjustable toward and from theprinting line, and to permit such adjustment, is rovided with ascrew-threaded stem 44 ig. 5) which extends through a-slot 45 in thecollating board to receive a thumb nut 46 behind the board. The gage baris also provided with a lug 47 projecting downwardly through a slot 48inthe board for guiding the lower end of the bar. By loosening the thumbnut 46, the gage may be adjusted toward and from the platen, and thenclamped in adjusted position by screwing up the nut. With thisconstruction, the gage or ga es may be adjusted to anyhorizontally-ru edsheet or printed form, provided with perforations to receive the bosses43. That is to say, the gage may be adjusted so that when a sheet isgag'ed thereon,a ruled line or a blank space designed to receivetypewritten matter, will register with the printing'line on the platen.

Fig. 3 illustrates'a method of arranging Work on the machine. As hereshown, the work comprises a loose-leaf ledger sheet 49 and a statementsheet 50, such as are employed, for example, in a system of bookeeplngwhere monthly statements may be made of an individual account, eachstatement comprising various items entered on different days of themonth. The statement 1s placed on the machine, with a ledger sheet.containing the record'of said account, each,

is made, and at a difierent position, and also that the sheets are notalways adjusted to a the same relative position, so that properpositions,

receive the first line of writing,

justment of the sheets,

it is important to provide means enabling the sheets to be quicklyadjusted individually to their and also to provide for bringing thesheets into accurate register. The present invention provides suchmeans. The ledger sheet is first placed on the machine as above noted,and moved upward over the collating board 32 into position to therebybringing openings 52 along the side margins of the sheet over the studs43, so that the studs may project into said openings, Whereby the sheetis accurately and definitely positioned on the board. The sheet may beheld on the studs by one thumb or finger of the operator, while theother sheet 50 is placed on the chute 30 behind the sheet/a9, andadvanced to the Fig. 3 position, where a number of openings 52 in itsmargin, engage studs 43.

The'gaging and insure refinement of adjustment by accuratelyand'definitely determining the positions of the sheets. Theyalso holdthe sheets against sliding on the work table or being "shifted out ofad-,

justment. After the sheets are adjusted, the

feed rolls 19, which during the arrangement of the sheets are held ofi'the platen, are returned to the platen, and hold the sheets in adjustedposition. The sheets being released from the hand of the operator, willspring away from the studs, which, owing to their rounded or taperingform, are self-freeing. This clearing of the sheet from the studs isalso aided by the advance of the sheet at the line-spacing operation,since the sheet above the platen and below the racks will tend to bulgeout and hence to withdraw from the bosses, if any of them should stillengage the sheet.

The led er and statement sheets, as shown inFig. 3, iave similar rulingsand headings,

. each sheet having columns for debits, credits,

balance, old balance, etc., and are designed for use on a combinedtypewriting and'cornputing machine, comprising mechanism formechanically effecting computations as the items are written. To clearlyset forth the method of using the present invention, the method ofentering the items shown on the mechanism.

studs 43 assist in the final adledger ing understood that the statementsheets on which-these items were simultaneously entered, are not shownon the drawing.

The ledger sheet having been placed on the machine, and a statementsheet (not shown), arranged thereover, a star 53 is printed in theright-hand side of a column 54; provided for that purpose. Thisindicates that the computing mechanism has been cleared, readyfor a newcomputation. The previous balance of $3.00", as shown at 55 (copied-fromthe old ledger sheet), is then printed in the old balance column, thisnumber being automatically placed on the computing mechanism as it isprinted. The platen is now line-spaced and moved to the right to receivean entry on the statement sheet and ledger sheet, includin date, terms,

-etc., and an amount of $4.00 written at 56 in the debit column, saidamount as it is written bein -run up on the computing he balance of$7.00 shown by the computin mechanism is now written in the' balancecolumn, the computing mechanism cleared, and a star 57 printed in theleft-hand side of the column 54, thereby showing that the correctbalance'has been written and the machine cleared for another computingoperation. Thework ma then beremoved from the machine and filed awayuntil it is desired to make another entry,

'when'the above order. of operations is re peated.

Assuming now cated on the sheet 49 have been made, and that it isdesired to make a new. entry, the ledger sheet 49 is first-placed on thema chine and advanced until the last'typewritten line, which in theexample shown includes the star 58, appears above the wings or gageplates 59, the upper edges of which "extend along the printing line,wfhe sheet may now be pressed against the work table bv the finger ofthe operator, so that the bosses 43 enter the perforations in the sheet,thereby squaring it to the platen and holding it in the exact line-spaceposition thatit occupied when receiving the preceding entry." Thestatement sheet 50 is now adjusted over the ledger sheet, so that thelast typewritten line of the statement (which in the example illustratedis a balance of -$3.00, shown at 60) is brought to the linegage plates59; the statement sheet being quickly and accurately gaged by the bosses43. The work is now in adjustment for receiving a new entry, which maybe made by repeating and underlies the latter, in practice this order isfrequently reversed, the ledger sheet being madenarrower than, andplaced over the underlying statement or'bill.

sheet 49 will first be explained, it be- "that all the entries indi-TrVariationsmay be resorted to within the scope of the invention, andportions of the improvements may be used without others.
